UnderstandingYour Septic System
A septic system is your home’s private wastewater treatment plant. Keeping it healthy is the first step to ensuring your property remains worry-free for decades. It’s an essential biological process that works silently to protect our local groundwater and the overall health of your landscape.
Why it matters
The Septic Tank
The watertight chamber where household waste is collected. Here, solids settle to the bottom and natural bacteria begin the decomposition process.
The Main Components
Inlet & Outlet Pipes
The network that directs wastewater from your home into the tank and safely transports the pre-treated liquid out to the treatment area.
The Drain Field
The final treatment step where pre-treated liquid is naturally filtered through soil, removing pathogens before they reach groundwater.
How the System Works
Understanding the natural biological process that safely treats wastewater for your home and environment is vital.
01
Collection & Tank Entry
All wastewater from your home travels through a main drainage pipe into the underground septic tank. This is where the initial separation and treatment process begins.
02
Separation & Scum Layering
Outside flow slows inside the tank, allowing solids to settle at the bottom as sludge while lighter fats and oils float to the top as scum. Natural bacteria work to break down the organic matter in the middle layer of clarified liquid.
03
Filtration & Outflow
The clarifies liquid, or effluent, passes through an outlet filter that prevents smaller solids from entering the drain field. This critical step protects the entire system from clogging and long-term damage.
04
Soil Treatment & Dispersal
Finally, the effluent flows into the drain field, percolating through the soil. Microorganisms in the soil finish the purification process, safely returning clean water to the groundwater supply.

Maintenance DO's
- Schedule professional pump-outs every 1-3 years.
- Use water-efficient fixtures to reduce loading.
- Direct surface water drainage away from the field.
- Keep accurate records of all maintenance work.
- Test your well water annually for safety.
Maintenance DON'Ts
- Don't flush wipes, hygiene products, or chemicals.
- Never pour cooking grease or oils down the drain.
- Avoid parking heavy equipment over the drain field.

Homeowner FAQs
How often should I pump my septic tank?
For most residential systems, a professional pump-out is recommended every 3 years. Regular pumping prevents sludge and scum solids from flowing into the drain field, which avoids system backups and costly repairs.
What are the signs of a failing septic system?
Common warning signs include slow drains, gurgling sounds in your plumbing, persistent sewage odors around the house, and unusually lush or wet patches of grass over the drain field area, even during dry weather.
Can I use a garbage disposal with a septic system?
It is generally not advised. Garbage disposals significantly increase the amount of solid waste entering your tank. If used, you may need to pump your system twice as often as a home without one to prevent clogs.
What should I avoid flushing down the drain?
Only flush human waste and toilet paper. Avoid flushing wipes (even those labeled flushable), cooking grease, harsh chemicals, feminine hygiene products, hair, and coffee grounds, as these do not break down and can cause blockages.
Where is my septic tank located?
The tank is usually located 10 to 25 feet away from the house. Look for an area where the grass is a different color, a small mound, or refer to your property's septic permit map usually found in the basement or with local authorities.
